The power brake booster crapped out on my 67 Gt500 . I sent the original off to be rebuilt by Allpro, it came back, put it on, a month later the engine starts going thoomp thoomp , the brakes lock up, and kaput. Turns out the newly rebuilt booster lost all its vacuum, I guess. Anyway, Id like to try and get it rebuilt again before going the aftermarket route, does anyone know a COMPETENT individual or company that can rebuild it ? Its a brake booster on a 67 GT500, power disc in front , drum in rear , 428 engine, 4 speed. Anybody know anyone or somewhere to send it ? Anyone ? Anyone ? Bueller ? Bueller ?
